Microsoftilla on jo pitkään ollut työn alla laite nykyisten Xbox Series X:n ja Xbox Series S:n seuraksi, ja tämä uusi vehje painottuisi ennen kaikkea suoratoistoon Xbox Cloud Gamingin hengessä. Koodinimenä on Keystone, ja toiminta olisi samanlaista kuin Chromecastilla ja Google Stadialla.
Xbox-pomo Phil Spencerin mukaan hintaa tällaisella vehkeellä ei paljoakaan olisi. Hän kertoi The Vergen podcastissa, että masiinalla olisi hintaa jossain välillä 99-129 dollaria. Spencer tähdensi senkin, että moista myyntihintaa on tällä hetkellä vaikea saavuttaa.
"With Keystone, [we're] still focused on it [and] when can we get the right costs, but when you've got Series S at $299, and like during the holidays you'll see some price promotion, you'll obviously have Series X higher, I think in order for a streaming-only box to make sense, the price delta to S has to be pretty significant. I don't want to announce pricing specifically, but I think you've got to be $129, $99, like somewhere in there for that to make sense in my view, that we just weren't there. We weren't there with the controller. And I love the effort. The reason it's on my shelf is the team rolled up their sleeves and in nine months they built that thing. And a bunch of us took it home and it worked. It worked really, really well."
